Altair Astro Premium Neutral Density Moon Filter :

Premium #ND96 filter boasting a plane polished glass surface giving very even light transmission. Not to be confused with cheaper Moon filters.

The metal machined casing offers a precise and orthogonal housing to the glass. Threaded to fit standard 1.25 inch eyepieces, Barlow lenses and 1.25 inch diagonal mirror barrels.

Why use a moon filter? Telescopes, even small diameter scopes, gather so much light that the moon is sometimes just too bright for comfortable observing. Fine details like lunar seas get washed out in the glare. Use of a Moon filter, a standard accessory for lunar observing, removes excess glare from lunar images, bringing out finer detail.
